Mario Testino

When I see Kate Moss out and about, I think she looks more beautiful than when her hairdresser and make-up artist try and make her look like something else. And I remember when Madonna first asked Versace to book me to shoot a campaign with her, she came to see me wearing hardly any make-up, and she looked incredible.

When I had photographed Prince William's mother, I brought along a CD of Dalida, a French singer, that we played on set all day to relax everyone. I decided to do the same thing for Catherine and William. The contrast of the contemporary informal music playing in the beautiful rooms with so much history caused a lot of laughter.

Madonna remains the most visible performer on the planet, as well as one of the wealthiest, but would anyone seriously say that artistic self-development is her primary motivating principle? She is too busy with Kabbalah, fashion merchandising, adoption melodramas, the gym, and ill-starred horseback riding to study art.

Painting and photography keep the creative channel open, and for an actor, it's to keep alive, it's to keep awake, it's to keep watching, it's to keep feeling, it's to keep enjoying, to keep that sensuality of feeling alive.
